"The main problem you seem to be having in class, if you don't mind me saying," Michelle said, while showing Wendy the textbook, "is that you might read the word correctly, but you don't use the right accompanying wand flick. For example, you might say 'Wingardium Leviosa' correctly, but your wand flick is wobbly, which means the spell misses the item you're trying to levitate completely."
